a siren HEEL Application filed August 6, 1931.l Serial No. 555,604.-

The invention relates to the heel of shoes and analogous foot gear,whereby to absorb and prevent shock and cushion any tendency to jar whenthe wearer is walking, running or in action.

The invention contemplates a shoe having an opening extending throughthe heel and sole thereof and enlarged at its lower end, a soft rubberinsert filling the opening and enlargement thereof, a metal strip moldedin the insert and having its projecting ends overlying the sole andtacked'thereto, a pad within the heel portion of the shoe overlying thesole and cemented thereto, said pad having an enlargement on its bottomside fitting a recess of corresponding shape formed in the top of therubber insert and a cushion of sponge rubber placed upon the pad, theseveral parts being cemented or made secure 1n any determinate way.

The invention furthermore has as an object the provision of a shoe heelin which the rub ber insert has molded therein a metal plate providedwith spurs which project to prevent slipping which is desirable in shoesfor athletes and those engaged in outdoor sports and games.

For a full understanding of the invention and the merits thereof,references is to be had to the drawings hereto attached and thesubjoined description, in which corresponding parts are designated inthe several views of the drawings and referred to in the specificationby like reference characters.

In the drawings Figure 1 is a fragmentary view in central longitudinalsection of the heel portion of a shoe illustrative of an embodiment ofthe invention.

Fig. 2 is a bottom view of the parts shown in Fig. 1 on a reduced scale.

Fig. 3 is a horizontal section through the heel portion just above thesole. v

Fig. 4 is a detail perspective view of the soft rubber insert and metalstrip molded therein.

Fig. 5 is a detail perspective view of the pad which overlies the heelportion of the sole.

Fig. 6 is a detail sectional view of the soft rubber insert having ametal plate provided with spurs embedded or molded therein,

Fig. 7 is a bottom plan: view of the metal plate provided with spurs.

- The shoe illustrated is of conventional structure andcomprises anupper 1, an outer sole 2, and a heel 3 formed of a plurality of leatherlifts. In accordance with the invention an opening is formed centrallythrough the heel 3 and extends through the; heel portion of the sole 2.-

This opening is enlarged at its lower end. A soft rubber insert issnugly fitted within the opening formed in the sole and heel of the shoeand the enlargement thereof and comprises a body portion 4 and anenlarged or head portion 5. This insert conforms to theopening formed inthe sole and heel of the shoe and preferably is a trifle larger thansaid openingsoas to be forced therein by 7 pressure, thereby insuring aclose and snug fit. It is obvious that cement'may bea'pplied tothe'insert to insure a water-tight joint between the heel and insertwhen the latter is in position. The application of cement to the insertalso assists materially in retaining the'insert in position against anycasual displacement. A recess 6 is formed in the top or upper end of theinsert and is adapted to receive a depending portion 7 of a, pad 8placed upon the heel portion of the sole 2. A metal strip'9 has itsmiddle portion deflected and embedded or molded in the body portion 4 ofthe insert. End portions of the strip 9 project and overlap the sole 2'adja cent the openingand are tackedto the sole, as indicated at 10. Ananchoring pin 11 is molded in the insert and engages the metal strip 9at the angle formed between the diverging portions, thereby assistingmate.

rially-in securing the metal strip and preventing its withdrawal fromthe insert.

The pad 8 is of soft rubber and of a size to snuglyfit within the heelportion of the shoe and overlie the sole 2. The forward end of the pad 8is tapered to a feather edge to prevent any appreciable projection atthe juncture of the pad with the sole 2. I

The pad 8 is formed with an enlargement 7 upon its bottom side which isadapted to snugly fit within the recess 6 formed in the top of therubber insert. A cushion 11 of sponge rubber overlies the pad 8 and itsforward end tapers and merges into the sole 2 to obviate the formationof any pronounced projection which would tend to cause discom fort. Y 7

When adapting the invention for shoes of athletes and those engaged inoutdoor sports and games, a metal plate 12 is molded 01'' embedded inthe lower or head portion 5 of the' rubber insert. This plate isprovided with spurs 13 which projectyso as to engage the surface andprevent slipping. The spurs 13 maybe welded 01' secured to the plate 12in any preferred Way. Projections 14' are ;pro vided one side of theplate 12 and assist materially in retainin the plate in predeterminedposition. These projections 14 may be formed by'pu'nc'hing' the plate 12or partly cutting portions therefrom and bending said portions so as toproject from a side of the plate to engage the rubber in whiehthe plateisembedded.

It is observed that the rubber inser't is disposed eentr'a'lly of theshoe heel, hence, occupies a position in line with the calcaneum or heelbone of the foot so as toefi'ectively cushion the shock and jar incidentto walking, running and other action. The head portion 5 of the rubberinsert may extend across thebottom side of the shoe heel or terminate atany point from the sides thereof. I Inpractic'e the insert will projectslightly below the bottom side-of'the shoe heel and will be roughened,as indicated at 15 in Fig. 2, inany manner to prevent slipping.

If desired, the plate '12 may have apertures 16 therein to'p'ermit thepassage of: nails or other suitable fastenings (not whereby to assist insecuring the plate 12 against displacement.

' Whatis claimed is 1. A shoe having an opening extending throughitsheel and sole, a rubber insert having a recess formed in its uppersurface fillfilling and secured Within said opening and 7 havinga-depression in its-top, a; pad disposed withinthe-heel portionoftheshoe and overlying .the sole thereof and formed with a dependingportionfitting the depression in the pad- In testimony whereof I havehereunto set my hand thisGday .o f August, 1931.
